Buy it! Use it! Enjoy it! Music and Speech like never seen before on the good old CPC and Plus computers.  :-*


If enough customers are interested I will support this great hardware with desired software.  :)


Now, what would you like to do with it today?  :'(

Good news - it is back in stock at Amazon - but it requires soldering:

In your case, you would need to disconnect the MP3 module first though... other than that, only a firmware update to v47 is required on the LS 3 side.

The MP3 module can be put to sleep. Maybe both can be used in the same time. I would try it, but got no MIDI things here at all.

I will try that. Did you already add the |mp3sleep command to the LS3 RSX ROM?

Two more shipping on Monday... picture for the owner.

For the time being, I have exactly ONE more DELUXE VERSION to sell (MP3 + RTC + SP0256-AL2), then I am out of parts - see 2nd picture.

PM if you want it! This is going to be the last one until November or so. Especially SP0256-AL2's are hard to get and cost me a fortune (~ 30 $ each).

30$ ?  :o


What about that: https://www.ebay.com/itm/1PCS-VOICE-SYNTHESIZER-IC-MICROCHIP-DIP-28-SP0256A-AL2/162779229313?epid=16010546217&hash=item25e665ec81:g:MkgAAOSwk1haHjqY
They are many other links about tham for less than 5$ inculding shipping fees.

Great find! I haven't seen them this cheap for a long time.

Bryce.

No, not a great find - I tried them and they are fake!!
I couldn't believe this story until I could verify it myself, but it IS true: they don't work:
http://www.smbaker.com/counterfeitfakejustplainbad-sp0256a-al2-chips
From this link, wrt to the Microchip chips:
Quote
The second set of bad chipsI decided to order more (Fool me once, shame on you. Fool me twice, shame on me). This time I chose a different seller, with chips that had a different manufacturer printed on them.

Here’s a picture:

Unlike the previous ones, these ones don’t output any speech at all. There is some noise that comes out of the output pin, and that noise varies according to what is on the address and data buses, even when the chip select input is not triggered. So it kinda makes annoying noise all the time.  It also glitched my RC2014 so that it wouldn’t run (probably by outputting signals to the address, data, or control buses).

I suspect these are just some random 28-pin IC that someone reprinted. I suppose it would be an interested exercise to apply to signals to the fake chips and use a logic analyzer to try to figure out what it’s actually doing, and determine that the chips actually are.

 Also:
https://www.eevblog.com/forum/projects/where-to-buy-an-sp0256-al2-speech-synthesizer-chip/
The only reliable source I have is this one - they are genuine GI and work.

If you don't believe it, buy one of the Ebay ones yourself and be amazed - they don't do anything. They don't even get warm.

2014 date code is highly suspicious !
Repackaged ones, emulated ones ?
Who knows ?

Indeed. They are fake. Don't buy them. See stories above. I tried them!

Time to make our own fake, emulating them on a STM32 or like.
I think there is C source and ROM dump somewhere.

Oops, didn't notice the dodgy date code, although I'd read that as Week 14, 2002 (which would still be questionable).
